My LG Tromm will spin (when I push start), but won't start the cycle (just keeps spinning)...intermittently. I have to turn off the power switch, turn it back on, reset the wash cycle and try again. Sometime I have to do this 3 times to get the cycle going. Sometimes, I have no problems at all and it starts right up into the wash cycle. I also intermittently get the door code (DE) at start with associated chime. If I open and close the door, that usually cures that problem. I don't know if these two issues are related or if I have two separate pending failures.

Any tips would be appreciated...before I start throwing parts at this thing i.e. a door switch...and whatever else I might need. Thanks!

I do not believe that either problems plays in to each other, they are separate. If the unit just seems to tumble slowly back and forth, similar to load sensing, without any other errors, I would believe the culprit would be the main pcb. Very hard to definitively diagnose, but the software is located in the MAIN pcb in the FRONT loaders... Wild is the man.

The Hall Sensor should arrive today or tomorrow. Just curious, if this doesn't fix the problem, I'm assuming it's the Mother Board (Main Board). Where is that located and how do you change it and what's the Part Number?

Main PCB is in the upper left of the cabinet. Having an updated Hall Effect sensor is great. However, I do believe the main pcb is the cause for your particular issue provided all wiring and connectors are ok.
